To investigate the impact of the internet in “traditional” market rules.


An opinion piece based on Michael Porter's arguments for the new economy.


Michael Porter's arguments for the new economy provide a useful starting point in the analysis of the environment. His arguments are based on exaggerated phenomena. Factors that determine a sector's profitability could be enriched with the innovation that prevails in the particular sector.


An attempt to criticize Porter's thoughts regarding internet and industry structure and to enrich the Porter's five forces model with the “power of innovation”.
